1. Industrial Rolling Side Table ($99) via Urban - Great as an end table, but put two together and you get a great coffee table!
2. Essex Printed Ottoman ($349) via West Elm - I saw this on Million Dollar Decorators (I just can't get enough of this show!) The ottoman doubles as a table and a comfortable place to sit on too!
3. 4+4 Coffee Table Design by Kutarq - This coffee table seems like it would be easy to build. Each module doubles as storage and seating. Reminds me of the chairs in Corbusier's Cabanon.
